Mutation - a spontaneous change in DNATypes of mutations -- gene or base: caused by a single base errorsubstitution (point): one base replaces anotheraddition: one base is inserteddeletion: one base is deletedchromosome mutation: a part of a chromosome is to blamedeletion: part of a chromosome is missingduplication: part of a chromosome is duplicatedinversion: part of a chromosome breaks off and reinserts backwardstranslocation: part of a chromosome from an unrelated chromosome attachesnon-disjunction: a whole chromosome is involved.Disorder: a negative effect of a mutation

Non-disjunction: when chromosomes don't separate correctly in meiosis, resulting in a gametes with too many or too few chromosomes. If such a gamete is involved in fertilization, the zygote (and baby if it develops) will have too few or too many chromosomes.
